Abstract

Most beaches which are in equilibrium depend for their maintenance upon a continuous supply of sediment. This supply rate has been estimated for instance for the beach at Santa Barbara to be of the order of magnitude of 350,000 cu. yards of sand per year (Johnson, 1948). As long as this supply rate prevails no accumulation of sand occurs on the beach. The sand must, therefore, be used up at the beach either by wear or by transport along the beach and, eventually, by deposition into some deeper water. A continual supply of that order of magnitude very rarely becomes available at the shore itself by wave erosion; instead the bulk of supply of sand to beaches usually is derived by rivers. The appraisal of the different river channels for their sediment supply to the beaches near their mouth becomes thus a major factor in the maintenance work of many beaches.
